Summary

Hieracium umbellatum, commonly known as Canadian Hawkweed, is a deciduous perennial herb native to a variety of habitats including open woodlands, forest edges, and meadows across North America, Europe, and parts of Asia. It typically grows to a height of 3-5 feet (0.9-1.5 meters) and a width of 0.5-0.7 feet (0.2-0.2 meters). This species is characterized by its clusters of small, daisy-like yellow flowers that bloom in the summer and fall, which are highly attractive to pollinators such as bees and butterflies.

Canadian Hawkweed is valued for its ease of maintenance and its ability to thrive in a range of soil conditions, from slow to fast drainage. It is often used in naturalized plantings, meadow gardens, and as a ground cover in larger landscapes. While it prefers full sun, it can tolerate part shade. Gardeners should be aware that this plant can spread aggressively by both seeds and stolons, potentially becoming invasive outside its native range. It is advisable to manage its spread to prevent it from outcompeting native vegetation.CC BY-SA 4.0
